Magnetoelastic effects in doped Fe2P
Z. Gercsi, E. K. Delczeg-Czirjak, L. Vitos +3
We use combine high resolution neutron diffraction (HRPD) with density functional theory (DFT) to investigate the exchange striction at the Curie temperature (TC) of Fe2P and to ex…
Frustrated Magnetism and Caloric Effects in Mn-antiperovskite Nitrides: Theory
J. Zemen, E. Mendive Tapia, Z. Gercsi +4
We model changes of magnetic ordering in Mn-antiperovskite nitrides driven by biaxial lattice strain at zero and at finite temperature. We employ a non-collinear spin-polarised den…
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…
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…
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…
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…
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…
Structurally driven metamagnetism in MnP and related Pnma compounds
Z. Gercsi, K. G. Sandeman
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…
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…
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…
