Visualization of ferromagnetic domains in TbNi${}_2$B${}_2$C and ErNi${}_2$B${}_2$C single crystals: Weak ferromagnetism and its coexistence with superconductivity

I. S. Veschunov, L. Ya. Vinnikov, S. L. Bud'ko +1

The magnetic flux structure in the basal plane, (001), of single crystals of superconducting (R = Er) and non-superconducting (R = Tb) RNi${}_2$B${}_2$C was studied by high resolution…
