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.

Magnetic and crystallographic properties of HoCo3B2

“…The RCo 3 B 2 compounds are paramagnetic at RT(295 K) and undergo a ferromagnetic transition at lower temperatures [2,3]. In the present work we report on the crystallographic and magnetic properties of HoCo 3 B 2 studied by neutron powder diffraction (NPD) and magnetic susceptibility measurements.…”

“…No long range magnetic order was detected above 10 K. r HoCo 3 B 2 belongs to the R n+1 Co 3n+5 B 2n (R ¼ lanthanide, n ¼ 0; 1; 2; 3; 1) family of compounds with n ¼ 1; crystallizing in the hexagonal (P6/mmm) CaCu 5 -type structure [1]. The RCo 3 B 2 compounds are paramagnetic at RT(295 K) and undergo a ferromagnetic transition at lower temperatures [2,3]. In the present work we report on the crystallographic and magnetic properties of HoCo 3 B 2 studied by neutron powder diffraction (NPD) and magnetic susceptibility measurements.…”

TDPAC Study of the Intermetallic Compound HfCo3B2

“…The magnetic and electronic properties of these compounds have been studied in the past using high-pressure x-ray diffraction technique [8], neutron diffraction, ac and dc-susceptibility measurements [9], Mössbauer studies [10,11], specific heat measurements [12], TDPAC measurements [13] and full potential Linearized Augmented Plane Wave (LAPW) calculations [14Y16].…”

Transport Properties of Hexagonal YCo5 and YCo3B2 Compounds

“…In the case of DyCo 3 B 2 at T = 5 K, the magnetic moment of 0.14 m B /Co, which is antiparallel to the Dy moment, is considered to be induced by the exchange field from the Dy spin [9]. Recently Caspi et al [12] performed neutron diffraction study of TbCo 3 B 2 to determine directly the magnetic moment of Tb and the induced moment on the Co-site.…”
