Outline of Final Research Achievements |
We measured the rotational invariance effect and the anisotropy effect in elastic mode C44 and the rotational invariance effect in elastic mode (C11-C12)/2 of single-crystalline PrT2Zn20 (T=Ir, Rh) using the special ultrasonic measurement system with the dilution refrigerator and the hybrid magnet which is constructed by High Field Laboratory for Superconducting Materials, Institute for Materials Research, Tohoku University. We found, for the first time, the spontaneous anisotropy in the rotational invariance effect for both samples PrT2Zn20 (T=Ir, Rh) between the higher and lower magnetic fields than the critical field at which the magnetic field induced phase appears. This result supports our prediction that the chiral symmetry in the novel vibronic state must be broken by the magnetic field.
