Field evolution of the magnetic structures in Er${}_2$Ti${}_2$O${}_7$ through the critical point

H. B. Cao, I. Mirebeau, A. Gukasov +2

We have measured neutron diffraction patterns in a single crystal sample of the pyrochlore compound Er${}_2$Ti${}_2$O${}_7$ in the antiferromagnetic phase (T=0.3\,K), as a function of th…
