“…2 to display a minimum near 110 K followed at lower temperatures by a peak at ≃ T 7.5 K max , a higher temperature than that, ≈ T 3.5 K max , reported in earlier measurements on CeB 6 in the 0-1 GPa pressure range [15,30,31]. Kobayashi et al [15] find that T max shifts to higher temperatures with pressure, reaching ∼7 K at 13 GPa. In the present experiment T max is also observed to increase with pressure (T max reaches 12.8 K at 7.7 GPa and 14.8 K at 12 GPa), the resistivity peak itself diminishing rapidly in size and finally disappearing at a pressure between 12 and 20 GPa.…”

“…Kobayashi et al [15] report that the prominent resistivity maximum in CeB 6 shifts from 3.6 K to ∼7 K at 13 GPa pressure, but there is no evidence for a transition to a Kondo insulating state as in SmB 6 [12]. There is also no evidence for a structural phase transition in CeB 6 at ambient temperature to 20 GPa [19].…”

“…So what is the possible mechanism for it? First of all, the magnetic structure of CeB 6 is extremely complicated [20][21][22][23] , and there is complex competition among different multipolar orders/interactions (dipolar, quadrupolar, and octupolar) at low temperature 24,28,33 . Initially, it seems that the transition near 20 K is magnetic.…”

“…In such a situation, it is interesting to study the pressure effect of PrB 6 and compare the results with those of CeB 6 . [12][13][14] The single crystals of PrB 6 used in the present study were prepared by a floating zone melting method by using an image furnace with four xenon lamps. 15 The electrical resistivity under pressure was measured by a standard four-probe ac method in magnetic fields up to 14.5 T along the ͓001͔ and ͓111͔ directions using a usual piston cylinder.…”
