Metamagnetism in single crystal γ‐Co(Pyridine)2Cl2

Abstract: Small (≳1 mg) single crystals of γ‐Co(pyr)2Cl2 have been grown and measurements of magnetic moment vs applied field H and temperature have been made for 0?H?54 kG and 1.25 K?T?4.2 K. At 1.25 K, metamagnetic transitions are observed along the a‐axis at ∠700 G; along the b‐axis at both ∠800 and ∠1500 G; and along the c‐axis at ∠ 4 kG. The low field susceptibilities show a maximum at T?3.4 K for each orientation. Magnetic saturation is not achieved at 54 kG; about 2.5 μB is achieved along the a*‐ or b‐axes, whereas a lower moment is achieved along the c‐axis, Along the b‐axis, the low field moment change is 1/2 the higher field moment change, suggesting a six‐sublattice magnetic structure.
