- 요약Susceptibility, original developed experimentally in the context of magnetic systems, is here applied to the magnetic octupole and two-dimensional electric quadrupole. PrV2Al20 and PrT i2Al20 are motivated as model systems, realizations of electric quadrupole and magnetic octupole order without significant competing lower-order multipolar order (such as magnetic order). Basic methods to probe the susceptibilities are then discussed, with emphasis on the careful use of properties of cubic symmetry to isolate the desired multipolar moments.A variety of experimental methods to probe the octupolar susceptibility are outlined, using combinations of strain and magnetic field to induce an octupolar moment. Limitations and advantages of each are noted. The AC elastocaloric effect, wherein oscillating strain is used to induce temperature oscillations in a material based on the entropy landscape thereof, is then motivated as a particularly powerful tool for probing the octupolar susceptibility. Experimental data using this technique on PrV2Al20, a system with realized magnetic octupolar order, is presented and analyzed, with a temperature-derivative of the octupolar susceptibility extracted. Lastly, the unique symmetry properties of the two-dimensional electric quadrupole and their implications are discussed in depth. Data is presented using the elastocaloric effect to probe the associated susceptibility in PrTi2Al20.The efficacy of the techniques used, and limitations thereof, are then discussed, along with potential means of improvement. Further potential applications of the techniques herein developed are briefly noted.
