Sorry for the delay in my responses. In fact, during the period of the conference, I have been tested positive for COVID-19.

No hysteresis was observed in our materials. So the entropy change is expected to keep its values under magnetization-demagnetization cycles.

Dear Varun, nice to see you here. The crystals present a high optical quality with tetragonal rectangular shape and typical size of 4 x 3 x 0.5 mm

Dear Nirmala, Thnaks a lot for your question. The giant MCE is particularly associated with the lowering of crystallographic symmetry from tetragonal to orthorhombic structure. This markedly affects the crystal electrical field configuration in TbVO4 and accordingly magnetism and MCE. More details on the nature of magnetism and MCEs in TbVO4 can be found in a paper that will appear soon in Physical Review Materials.
