The magnetism of TbNi sub 5 at low fields

Magnetic susceptibility and magnetization measurements were made on a polycrystalline sample of TbNi sub 5 . The compound is ferromagnetic for T < T sub h approx = 17K at any applied magnetic field. For temperatures between T sub h , and T sub N = 23K and magnetic fields smaller than a critical f...

Description
Summary:Magnetic susceptibility and magnetization measurements were made on a polycrystalline sample of TbNi sub 5 . The compound is ferromagnetic for T < T sub h approx = 17K at any applied magnetic field. For temperatures between T sub h , and T sub N = 23K and magnetic fields smaller than a critical field H sub c = 400 Oe, the compound is helimagnetic. When H > H sub c or T < T sub h , the anisotropy in the basal plane increases, and the compound becomes ferromagnetic.
