KV3Sb5 single crystal

Higher-order oscillatory PHE

This single crystal exhibits unconventional higher-order oscillatory planar Hall effect under in-plane magnetic fields, distinct from the two-fold oscillations in conventional materials, revealing strong coupling among lattice, magnetic, and electronic structures.

Advantages

Planar Hall effect shows higher-order oscillations, violating the empirical rule allowing only two-fold symmetrical oscillations

Oscillations vanish near the charge density wave transition temperature

Oscillations exhibit strong magnetic field and temperature dependence
