Query: Complex magnetic phase diagram with a small phase pocket in a
  three-dimensional frustrated magnet CuInCr$_{4}$S$_{8}$   Frustrated magnets with a strong spin-lattice coupling can show rich magnetic
phases and the associated fascinating phenomena. A promising platform is the
breathing pyrochlore magnet CuInCr$_{4}$S$_{8}$ with localized $S=3/2$
Cr$^{3+}$ ions, which is proposed to be effectively viewed as an $S=6$
Heisenberg antiferromagnet on the face-centered-cubic lattice. Here, we unveil
that CuInCr$_{4}$S$_{8}$ exhibits a complex magnetic phase diagram with a small
phase pocket (A-phase) by means of magnetization, magnetostriction,
magnetocapacitance, and magnetocaloric-effect measurements in pulsed high
magnetic fields of up to 60~T. Remarkably, the appearance of A-phase is
accompanied by anomalous magnetostrictive and magnetocapacitive responses,
suggesting the emergence of helimagnetism in contrast to the neighboring
commensurate magnetic phases. Besides, the high-entropy nature is confirmed in
the high-temperature side of A-phase. These features are potentially related to
a thermal fluctuation-driven multiple-$q$ state caused by the magnetic
frustration, which has been theoretically predicted but yet experimentally
undiscovered.
