Field-induced transitions have been observed earlier in manganese monopnictide polycrystals. However, the role played by anisotropy in these second order transitions remained unclear. In this contribution we present magnetization data for 4.2 K 0.83

The anisotropy of the magnetization of MnAs1−xSbx single crystals is investigated in the temperature range 4.2 K < T < 600 K, for fields up to 0.6 T and concentrations x = 1, 0.5, and 0.1. The first spin reorientation temperature of MnSb, Ts1 = 270

Microwave absorption in MnAs poly- and single crystals below Tu are identified as FMR whose resonance frequencies are determined by magnetocrystalline anisotropy. It is found that K1 = −5.7 × 105 J/m3; K2 = 2.1 × 105 J/m3; K3 = −2.0 × 105 J/m3

The temperature dependence of the resistivities of some MnAs1−xSbx and CryMn1−ySb single crystals and polycrystals have been measured for 4.2 K < T < 650 K and different crystal axes. While magnon scattering appears to be dominant for near-stoich

The anomalous Hall effect ϱH and the magnetoresistance Δϱ/ϱ of CrxMn1−xSb single crystals with x = 0.4 are measured for 4.2 K < T < 300 K, 0 < H < 7T. The Hall effect appears to be determined by anisotropic (magnon) spin scattering while the (c

The magnetic behaviour of NiAs-type (Co 1− y Fe y ) 1− x Te ( x = 0.36) has been characterized by magnetization measurements at low temperatures (4.2–300 K). All samples investigated ( y = 0.3, 0.5, 0.7) were weakly ferromagnetic with a small m
