Orbital magnetism in two-leg ladder cuprate
We discovered the existence of a new kind of short-range magnetism in the two-leg ladder (Sr,Ca)14Cu24O41 family of cuprates [1]. Observed for the Ca contents x = 5 and 8, this magnetism develops within the two-leg ladders and exhibits increasing correlations with increasing hole-doping. Its magnetic scattering further displays a very specific momentum dependence, the hallmark of a theoretically predicted loop current magnetism in such a material [2, 3]. Our discovery brings a novel insight onto the nature of the magnetic properties of hole-doped two-leg ladder cuprates and suggests that a loop current phase could act as a precursor to the long range magnetic order state at larger Ca content. We propose to investigate the existence of possible magnetic fluctuations related to the LCs like phase for the x=8 and 12 Ca-doped samples using polarized neutrons To this aim, we ask for 13 days on IN22 equipped with CRYOPAD.
