Magnetic properties of TbCo3B2 studied by neutron diffraction, magnetization, and ac-susceptibility measurements

Abstract

Neutron-diffraction measurements on TbCo3B2, with the isotope B11, show ferromagnetic structure below 35(2) K. Ordered magnetic moments of Tb and Co were found to be in the basal planes directed parallel to each other. The Tb ordered moment is significantly smaller than its free-ion value. The Co ordered moment is nearly zero. Ac-susceptibility and SQUID magnetometer measurements agree with the neutron results.
