Abstract:
Low-temperature magnetic properties of Er2Zr2O7 were studied by magnetization measurements on a newly prepared single crystal. Simultaneously, powder neutron diffraction was employed to investigate its microscopic properties down to 0.3 K. Our low-temperature data demonstrate the presence of a magnetic signal (short-range correlations) by (i) bifurcation of zero-field-cooled (ZFC) and field-cooled (FC) data, and (ii) diffuse magnetic scattering signal developing well in agreement with the temperature development of bulk properties. The presented data are discussed in the frame of a spin-glass ground state in Er2Zr2O7.
