“…Details of single-crystal synthesis and characterization are described elsewhere. 24,25 The compositional homogeneity and crystal morphology were analyzed by x-ray diffraction (XRD), scanning electron microscopy (SEM), and energy-dispersive x-ray spectroscopy (EDX). All results confirmed the high homogeneity of all crystals studied.…”

We report an experimental and computational study of single-crystal NdFeO3, which features two inequivalent magnetic sublattices, namely, Fe and Nd sublattices that are coupled in an antiparallel fashion. This paper reveals that a strong interaction between 3d and 4f electrons of the two sublattices along with a spin-lattice coupling drives an extremely interesting magnetic state that is highly sensitive to the orientation and history of weak magnetic field. The following phenomena are particularly remarkable: (1) sharply contrasting magnetization M(T) along the a and c axes; (2) a first-order spin switching along the a axis below 29 K when the system is zero-field-cooled; and (3) a progressive magnetization reversal when the system is field-cooled. The intriguing magnetic behavior is captured in our first-principles density functional theory calculations.

“…It was observed that the boule becomes a single crystal after several centimeters of growth [8]. As can be seen from the experimental results of different growth rates (2.5-24 mm/h) [8][9][10][11], high growth rate could lead to cracking in the growth process owing to the large thermal stresses. The thermal stress easily induces cracking at the grain boundary.…”

“…Most of the foundational researches for orthoferrites ideally require samples in single crystal form and the optical-floatingzone growth is an excellent technique and widely used to prepare the single crystal orthoferrites [8][9][10][11][12]. During the crystal growth progress by the floating-zone method, the quality of crystal usually depends on factors such as stability of the molten zone, quality of feed and seed rods, rotation rate, temperature distribution, atmosphere environment, chemical composition, and especially the growth rate.…”

Although many efforts have been made [8][9][10][11], the crystals still suffer from many kinds of disadvantages such as very small size, voids, dislocation, cracks, and so on.…”

“…During the growth process, the molten zone moved upwards, with the seed rod (lower shaft) and the feed rod (upper shaft) counter rotating in a gas flow. The compositional homogeneity and crystal morphology analyzed by X-ray diffraction (XRD) and scanning electron microscopy (SEM) with energy-dispersive X-ray spectroscopy (EDX) have been used to confirm the high quality of the single crystals [15][16][17].…”

Multiferroic materials are currently the subject of intensive research worldwide, because of both their fundamental scientific problems and also possible technological applications. Among a number of candidates in the laboratories, compounds consisting of rare earth and transition metal perovskite oxides have very unusual structural and physical properties. In contrast to the so-called type I multiferroics, ferroelectricity may be induced by magnetic ordering or by applying external fields. In this review, the recent progress on the experimental and theoretical studies of some selected type II multiferroics is presented, with a focus on the perovskite oxides containing rare earth and transition metal elements. The rare earth orthoferrite crystals, rare earth titanate strained film, and rare earthbased superlattices are systematically reviewed to provide a broad overview on their promising electric, magnetic, and structural properties. The recent experimental advances in single-crystal growth by optical floating zone method are also presented. First-principles investigations, either supported by experimental results or awaiting for experimental verifications, are shown to offer useful guidance for the future applications of unconventional multiferroics.
