Abstract
Single crystals of cobalt‐doped thallium manganese fluoride (TlMn1−xCoxF3) have been studied by antiferromagnetic resonance for cobalt concentrations of 0≤x≤0.001. In this range the antiferromagnet remains cubic at 4.2°K, with its crystalline anisotropy varying linearly with cobalt concentration from K1/M = −5.1 Oe for pure TlMnF3 to +8.2 Oe, passing through zero for x=0.0004. Other magnetic properties, such as Néel temperature and exchange field, are unaffected by the small cobalt concentrations. Multiple non‐equivalent equilibrium spin‐orientation states, which have been observed in spin‐flopped resonance in the 〈100〉 and 〈110〉 crystal planes when K1/M is greater than zero, are described.This publication has 4 references indexed in Scilit:
