“…It is worth mentioning that besides the geometrically driven multiferroics of the h-RMnO 3 and the BaMF 4 families, different non-magnetic geometric ferroelectrics exist which potentially host unusual functional domain walls. This includes potassium selenate K 2 SeO 4 [81] and other A 2 BX 4type halides, such as Cs 2 CdI 4 and Rb 2 CdI 4 [82,83], as well as the Ruddlesden-Popper compound (Ca,Sr) 3 Ti 2 O 7 [84]. Although the discussion of these non-multiferroic materials goes beyond the scope of this review, it is noteworthy that (Ca,Sr) 3 Ti 2 O 7 has recently been demonstrated to host electrically conducting walls, foreshadowing interesting domain wall physics to emerge in geometric ferroelectrics that are yet to be explored in all detail [84].…”

During the last decade a wide variety of novel and fascinating correlation phenomena has been discovered at domain walls in multiferroic bulk systems, ranging from unusual electronic conductance to inseparably entangled spin and charge degrees of freedom. The domain walls represent quasi-2D functional objects that can be induced, positioned, and erased on demand, bearing considerable technological potential for future nanoelectronics. Most of the challenges that remain to be solved before turning related device paradigms into reality, however, still fall in the field of fundamental condensed matter physics and materials science. In this topical review seminal experimental findings gained on electric and magnetic domain walls in multiferroic bulk materials are addressed. A special focus is put on the physical properties that emerge at so-called charged domain walls and the added functionality that arises from coexisting magnetic order. The research presented in this review highlights that we are just entering a whole new world of intriguing nanoscale physics that is yet to be explored in all its details. The goal is to draw attention to the persistent challenges and identify future key directions for the research on functional domain walls in multiferroics.

“…However, upon heating, Cs 2 HgI 4 and Cs 2 CdI 4 convert from the monoclinic structure of Sr 2 GeS 4 -type (α-phase) to the orthorhombic structure of β-K 2 SO 4 -type (β-phase), and this transmutation is identified as α → β phase transition [19] . For Cs 2 HgI 4 , the α → β phase transition transpires at around 520 K [20] or 523 K [12] . Shimizu et al [20] showed that α → β transformation in Cs 2 HgI 4 is a first-order phase transition using Differential Thermal Analysis (DTA).…”
