Effects of disorder on the magnetic properties of the Heusler alloy VFeAl
Ross Smith, Zsolt Gercsi, Rui Zhang +3
Magnetic properties of multicomponent alloys depend sensitively on the degree of atomic order on the different crystallographic sites. In this work we demonstrate the magnetic cont…
RuMnAl thin films
K. E. Siewierska, H. Kurt, B. Shortall +7
The cubic Heusler alloy RuMnAl is grown in thin film form on MgO and MgAlO substrates. It is a highly spin-polarised ferrimagnetic metal, with weak magnetoc…
Au4Mn, a localized ferromagnet with strong spin-orbit coupling, long-range ferromagnetic exchange and high Curie temperature
Yangkun He, Zsolt Gercsi, Rui Zhang +8
Metallic Mn-based alloys with a nearest-neighbor Mn-Mn distance greater than 0.4 nm exhibit large, well-localized magnetic moments. Here we investigate the magnetism of tetragonal…
Rare-earth-free noncollinear metallic ferrimagnets Mn4-xZxN with compensation at room temperature
Rui Zhang, Yangkun He, Daniel Fruchart +2
Compensated ferrimagnets, like antiferromagnets, show no net magnetization but their transport and magneto-optic properties resemble those of ferromagnets, thereby creating opportu…
Single pulse all-optical toggle switching of magnetization without Gd: The example of Mn2RuxGa
C. Banerjee, N. Teichert, K. Siewierska +6
Energy-efficient control of magnetization without the help of a magnetic field is a key goal of spintronics. Purely heat-induced single-pulse all-optical toggle switching has been…
Piezomagnetic effect as a counterpart of negative thermal expansion in magnetically frustrated Mn-based antiperovskite nitrides
Jan Zemen, Zsolt Gercsi, Karl G. Sandeman
Electric-field control of magnetization promises to substantially enhance the energy efficiency of device applications ranging from data storage to solid-state cooling. However, th…
Thermal-history dependent magnetoelastic transition in (Mn,Fe)2(P,Si)
X. F. Miao, L. Caron, Z. Gercsi +4
The thermal-history dependence of the magnetoelastic transition in (Mn,Fe)2(P,Si) compounds has been investigated using high-resolution neutron diffraction. As-prepared samples dis…
Electronic structure, metamagnetism and thermopower of LaSiFe and interstitially doped LaSiFe
Z. Gercsi, N. Fuller, K. G. Sandeman +1
We present a systematic investigation of the effect of H, B, C, and N interstitials on the electronic, lattice and magnetic properties of La(Fe,Si) using density functional…
The dynamics of spontaneous hydrogen segregation in LaFeSiH
Oliver L. Baumfeld, Zsolt Gercsi, Maria Krautz +2
By means of time- and temperature-dependent magnetization measurements, we demonstrate that the timescale of hydrogen diffusion in partially-hydrogenated LaFeSiH i…
Magnetic structures of Mn3-xFexSn2: an experimental and theoretical study
Q. Recour, V. Ban, Z. Gercsi +3
We investigate the magnetic structure of Mn3-xFexSn2 using neutron powder diffraction experiments and electronic structure calculations. These alloys crystallize in the orthorhombi…
Magneto-elastic coupling and competing entropy changes in substituted CoMnSi metamagnets
A. Barcza, Z. Gercsi, H. Michor +4
We use neutron diffraction, magnetometry and low temperature heat capacity to probe giant magneto-elastic coupling in CoMnSi-based antiferromagnets and to establish the origin of t…
Tuning the metamagnetism of an antiferromagnetic metal
J. B. Staunton, M. dos Santos Dias, J. Peace +2
We describe a `disordered local moment' (DLM) first-principles electronic structure theory which demonstrates that tricritical metamagnetism can arise in an antiferromagnetic metal…
Designed Metamagnetism in CoMnGe_{1-x}P_{x}

We extend our previous theoretical study of Mn-based orthorhombic metamagnets to those that possess large nearest neighbour Mn-Mn separations (d1>3.22A). Based on our calculations,…

We investigate the structural conditions for metamagnetism in MnP and related materials using Density Functional Theory. A magnetic stability plot is constructed taking into accoun…
Giant magneto-elastic coupling in a metallic helical metamagnet
A. Barcza, Z. Gercsi, K. S. Knight +1
Using high resolution neutron diffraction and capacitance dilatometry we show that the thermal evolution of the helimagnetic state in CoMnSi is accompanied by a change in inter-ato…
