Li(Zn,Co,Mn)As: A bulk form diluted magnetic semiconductor with Co and Mn co-doping at Zn sites

“…After this discovery, several new types of bulk forms of DMSs with decoupled spins and charges injections have been reported. [17][18][19][20][21][22][23][24][25][26][27] The availability of bulk forms of specimens make it possible to investigate the microscopic magnetism of DMSs based on typical bulk probes, 28 such as nuclear magnetic resonance (NMR), 29 muon spin relaxation (µSR), 17,18,20,30 neutron scattering, absorption spectroscopy (XAS), 31 resonance photoemission spectroscopy (RPES), 31 and angle-resolved photoemission spectroscopy (ARPES). 32 It has been confirmed by the XAS measurements that the valence of Mn in (Ba,K)(Zn,Mn) 2 As 2 is bivalence.…”

New Fluoride-arsenide Diluted Magnetic Semiconductor (Ba,K)F(Zn,Mn)As with Independent Spin and Charge Doping

“…The two different layers are stacked in an AB AB sequence along the c -axis, resulting in the compound’s quasi two-dimensional nature. The lattice parameters were calculated to be a  = 4.2380 Å and c  = 9.5284 Å, which are similar with that of LaOZnSb ( a  = 4.2267 Å and c  = 9.538 Å), the parent compound for “1111” oxide-arsenide diluted magnetic semiconductors19. This is caused by big size difference between La 3+ (1.061 Å) and Ba 2+ (1.35 Å) as well as between Sb 3− (0.76 Å) and As 3− (0.58 Å).…”

“…Shortly after, another new type of bulk ferromagnetic DMS (Ba,K)(Zn,Mn) 2 As 2 was synthesized with much higher T C up to 230 K1617. More recently, several types of bulk DMSs with decoupled spin & charge doping have been successfully fabricated, including Li(Zn,Mn)P18, (La,Ca)(Zn,Mn)SbO19, (La,Ba)(Zn,Mn)AsO20, (La,Sr)(Cu,Mn)SO21, (Sr,Na)(Cd,Mn) 2 As 2 22, and ( A ,Na)(Zn,Mn) 2 As 2 ( A  = Ca, Sr,)2324.…”

“…The successful discovery of superconductivity in the F doped LaFeAsO has aroused extensively studies on the compounds with the ZrCuSiAs-type structure and the relationship with other structures192025. In this article, we report a new fluoride-arsenide ferromagnetic semiconductor (Ba,K)F(Zn,Mn)As, which shares the same structure as that of “1111” iron-based superconductor Sr 1−x Sm x FFeAs25 and Ba 1−x Sm x FFeAs26 (the tetragonal ZrCuSiAs-type structure).…”

(Sr 3 La 2 O 5 )(Zn 1−x Mn x ) 2 As 2 : A bulk form diluted magnetic semiconductor isostructural to the “32522” Fe-based superconductors

“…More recently, several more bulk DMS systems have been reported. Firstly, Ding et al reported the ferromagnetic ordering below T C ∼ 40 K in a "1111" type (La,Ba)(Zn,Mn)AsO system [9]; Han et al reported the ferromagnetism in (La,Ca)(Zn,Mn)SbO semiconductor [10] and Yang et al reported the fabrication of (La,Sr)(Cu,Mn)SO DMS with T C ∼ 210 K [11]. Secondly, Zhao et al reported the "122" type DMS systems, (Ba,K)(Zn,Mn) 2 As 2 , which has T C as high as 180 K [12], and Yang et al observed the ferromagnetic transition below T C ∼ 17 K and a large negative magnetoresistance in (Ba,K)(Cd,Mn) 2 As 2 [13].…”
