Electrical transport properties of micrometer-sized samples of the rare-earth chiral magnet YbNi3Al9

We investigate electrical transport properties of micrometer-sized samples of the rare-earth-based monoaxial chiral magnetic crystal YbNi3Al9 in order to characterize chiral magnetic structures. The magnetoresistance (MR) data exhibit discrete changes, supporting the formation of the chiral spin soliton lattice (CSL) in YbNi3Al9. Reversal and lock-in behavior of the MR signal are significant features during the CSL formation, which contrast with hysteresis behavior reported in a prototype monoaxial chiral magnetic crystal of CrNb3S6. The magnetic phase diagrams are provided based on the electrical transport properties in micrometer-sized YbNi3Al9 crystals.
