“…57 F e Mössbauer spectroscopy and muon-spin relaxation (µSR) studies of polycrystalline TbNi 2 B 2 C [9] confirmed the presence of a small ferromagnetic component below about 8 K previously observed via neutron diffraction [7] and magnetization measurements [10,11].…”

Temperature dependence of low-energy phonons in magnetic nonsuperconducting TbNi2B2C

We report temperature dependence of low-energy phonons in magnetic nonsuperconducting TbNi2B2C single crystals measured by inelastic neutron scattering. We observed low-temperature softening and broadening of two phonon branches, qualitatively similar to that previously reported for superconducting RNi2B2C (R = rare earth, Y ) compounds. This result suggests that superconductivity in TbNi2B2C compounds is absent not because of weak electron-phonon coupling but as a result of pair breaking due to magnetism.

“…In fact, the magnetic hyperfine field at the Ni site, which could act as the pair-breaking field at Ni site, was observed in the Mössbauer spectroscopy. 10 The study of pseudoquaternary compound, Er 1Ϫx Tb x Ni 2 B 2 C was reported. It was conjectured that the weak-ferromagnetic component does not directly affect the superconductivity.…”

The magnetic and superconducting properties in a series of pseudo-quaternary compounds Y 1Ϫx Tb x Ni 2 B 2 C were investigated by the temperature-dependent magnetization M (T) for applied field parallel and perpendicular to the c axis and by in-plane resistivity, (T). There was a large anisotropy in M (T), which is attributed to the crystalline electric field effects. As the Tb concentration x is increased, the superconducting transition temperature T c decreases and disappears rapidly in the vicinity of xϭ0.4 while the Néel temperature T N appears abruptly near xϭ0.4 and increases with Tb content. In addition, the increase of M (T) at low temperatures below T N was observed for xу0.4, of which the onset temperature T WF is regarded as development of weak-ferromagnetic component. T WF was also in proportion to the Tb content x accompanied by T N . The linear decrease of T c for dilute Tb concentration seems to follow an Abrikosov-Gor'kov expectation, while the sudden destruction of T c near xϭ0.4 seems to have close correlation with the emergence of magnetic states, i.e., antiferromagnetic and weak-ferromagnetic states. Possible scenarios for the correlation are discussed.

“…Furthermore, 57 Fe Mössbauer and SR experiments have indicated the onset of weak ferromagnetism through a reduction in the hyperfine field and the electronic spin fluctuation rate below T WFM . 19 In this paper, we report on recent x-ray magnetic circular dichroism ͑XMCD͒ experiments on TbNi 2 B 2 C designed to directly probe the onset of a ferromagnetic component below T WFM associated with the Tb ions. An XMCD experiment probes the difference, c ϭ( ϩ Ϫ Ϫ )/( ϩ ϩ Ϫ ), in the absorption of x rays by a sample with the magnetic moment parallel ( ϩ ) and antiparallel ( Ϫ ) to the helicity of the incident photon beam.…”

X-ray magnetic circular dichroism measurements were performed on TbNi 2 B 2 C in order to confirm the weak ferromagnetism reported for this material at low temperatures. Below approximately 8 K, an increase in the dichroic signal was observed at the Tb L III edge, consistent with the onset of weak ferromagnetism involving the Tb ions. At an external magnetic field of 500 G, the ferromagnetic order parameter was obtained, and is in good agreement with the bulk magnetization data measured by a SQUID magnetometer.
