Exploring the low temperature spin dynamics in Tb?Zr???Ti?O? (x = 0, 0.50)

Abstract: We are studying Tb?Zr???Ti?O? series where substitution of Ti changes the structure from a fluorite to a disordered pyrochlore phase. This Ti doping influences the ground state of Tb³? ions, disrupts the glassy spin state seen in Tb?Zr?O?, and leads to the development of dynamic spin fluctuations, which are key features of a spin liquid state. Heat capacity measurements show a peak near 4.9 K at zero field, which remains in the Ti-doped sample but with reduced intensity. The magnetic heat capacity, revealing an unexpected peak that shifts to lower temperatures and is suppressed above 1 T, evolving into a broad Schottky-type anomaly.AC susceptibility of Tb?Zr?O? also shows a notable deviation at 4.9 K, which weakens above 1 T. Beyond this field, a spin-freezing-like feature appears, similar to that observed in Dy?Zr?O? and Ho?Zr?O?.)). The studies of these compound are essential for gaining a deeper understanding of their unusual the magnetic and quantum behavior is at very low temperatures.
