Strain control of magneto-optical properties of ultra-thin Ni-Mn-Ga films grown by magnetron sputtering
M. Makeš, P. Veřtát, M. Rameš +5
Ultra-thin epitaxial Ni-Mn-Ga films, 10-15 nm thick, were grown by magnetron sputtering on MgO(001), either directly on the substrate or on a Cr buffer, and studied by X-ray diffra…
Ultrafast control of spin order by linearly polarized light in noncollinear antiferromagnetic metals
J. Kimak, M. Nerodilova, K. Carva +15
The non-thermal optical control of magnetic order offers a promising route to ultrafast, energy-efficient information technologies. Although optical manipulation of magnetism in me…
Antiphase boundaries in Ni-Mn-Ga single crystal - experiment and model
O. Heczko, F. Maca, V. Drchal +3
Thermally induced antiphase boundaries (APBs) in ferromagnetic, ordered Ni-Mn-Ga single crystal exhibit complex, irregular shapes and closed loops without any lattice plane prefere…
Stress-induced Martensitic transformation in epitaxial Ni-Mn-Ga thin films and its correlation to optical and magneto-optical properties
M. Makeš, J. Zázvorka, M. Hubert +5
The optical and magneto-optical properties of thin epitaxial Ni-Mn-Ga films, with thicknesses ranging from 8 to 160 nm, were investigated across the spectral range of 0.7-6.4 eV. T…
Analysis of magneto-optical Kerr spectra of ferrimagnetic MnN
Jan Zemen
Simulations of magneto-optical Kerr effect in biaxially strained MnN are performed using density functional theory and linear response theory. We consider three ferrimagnetic p…
Identifying the octupole Antiferromagnetic domain orientation in MnNiN by scanning Anomalous Nernst Effect microscopy
F. Johnson, J. Kimák, J. Zemen +9
The intrinsic anomalous Nernst effect in a magnetic material is governed by the Berry curvature at the Fermi energy and can be realized in non-collinear antiferromagnets with vanis…
Room temperature weak collinear ferrimagnet with symmetry driven, large intrinsic magneto-optic signatures
F. Johnson, J. Zázvorka, L. Beran +4
Here we present a magnetic thin film with a weak ferrimagnetic (FIM) phase above the Néel temperature ( = 240 K) and a non-collinear antiferromagnetic (AFM) phase below, exh…
Ab-initio based analytical evaluation of entropy in magnetocaloric materials with first order phase transitions
Marco Piazzi, Jan Zemen, Vittorio Basso
We combine spin polarised density functional theory and thermodynamic mean field theory to describe the phase transitions of antiperovskite manganese nitrides. We find that the inc…
