    We report on ultrasonic and magnetocaloric-effect measurements of the hexagonal antiferromagnet Dy3Ru4Al12 having a distorted kagome lattice. We observed a pronounced softening of the transverse modulus, C44, above 30 T applied along [100], indicating an as-yet-unidentified magnetic field induced phase transition. We determined the field-temperature phase diagrams using pulsed magnetic fields up to 55.2 T, applied along [100] and [001]. Optimizing crystal-electric-field parameters within the mean-field approximation, we conclude that the enhancement of the field induced phase-transition temperature is due to electric quadrupolar and magnetic octupolar mediated interactions. We propose that the order parameter of the magnetic field induced phase transitions is the electric quadrupole Ozx, facilitated by octupole-mediated interactions.
