Onset of a skyrmion phase by chemical substitution in MnGe chiral magnet
E. Altynbaev, N. Martin, A. Heinemann +4
We study the evolution of the magnetic phase diagram of MnFeGe alloys with concentration () by small-angle neutron scattering. We unambiguously…
Physical properties of (Mn 0.85 Fe 0.15) Si along the critical trajectory
A. E. Petrova, Dirk Menzel, S. M. Stishov
We report results of studying the magnetization, specific heat and thermal expansion of a single crystal with nominal composition Mn 0.85 Fe 0.15 Si . We found no thermodynamic evi…
Thermodynamics of symmetric spin--orbital model: One- and two-dimensional cases
V. E. Valiulin, A. V. Mikheyenkov, K. I. Kugel +1
The specific heat and susceptibilities for the two- and one-dimensional spin--orbital models are calculated in the framework of a spherically symmetric self-consistent approach at…
Quantum phases of SrCu2(BO3)2 from high-pressure thermodynamics
Jing Guo, Guangyu Sun, Bowen Zhao +9
We report heat capacity measurements of SrCu(BO) under high pressure along with simulations of relevant quantum spin models and map out the phase diagram of the…
