    "abstract": "The contribution of parity-violating effects to the phase transition of the\nD-/L-alanine crystals was confirmed by 1H CRAMPS solid state NMR, DC-magnetic\nsusceptibilities and ultrasonic measurements. It was found that the spin\nrelaxation mechanism of alpha-H nucleus of D-alanine molecule is different from\nL-alanine and the effect is stronger than that of L-alanine. In addition,\nD-alanine undergoes a magnetic phase transition at a field of 1.0T, which is\nconfirmed by a peak-form ultrasonic attenuation curve. DC-magnetic\nsusceptibilities measurements of L-alanine also indicate abnormal magnetic\nproperties, which is accompanied by a step-form ultrasonic attenuation jump and\nits mechanism seems different from that of D-alanine. The phase transition is\nconsidered to act as a cooperating amplification mechanism of the P-odd effects\nat the molecular level.",
