[M(Hdapsc)]-[Cr(CN)] (M = Mn, Co) Chain and Trimer Complexes: Synthesis, Crystal Structure, Non-Covalent Interactions and Magnetic Properties.

Four new heterometallic complexes combining [M(Hdapsc)] cations with the chelating Hdapsc {2,6-diacetylpyridine-bis(semicarbazone)} Schiff base ligand and [Cr(CN)] anion were synthesized: {[M(Hdapsc)]Cr(CN)K(HO)(EtOH)}·1.2(HO), M = Mn () and Co (), {[Mn(Hdapsc)]Cr(CN)(HO)}Cl·HO () and {[Co(Hdapsc)]Cr(CN)(HO)}Cl·2EtOH·3HO (). In all the compounds, M(II) centers are seven-coordinated by NO atoms of Hdapsc in the equatorial plane and N or O atoms of two apical -CN/water ligands.

Performance Validation of a Planar Hall Resistance Biosensor through Beta-Amyloid Biomarker.

Magnetic sensors have great potential for biomedical applications, particularly, detection of magnetically-labeled biomolecules and cells. On the basis of the advantage of the planar Hall effect sensor, which consists of improved thermal stability as compared with other magnetic sensors, we have designed a portable biosensor platform that can detect magnetic labels without applying any external magnetic field. The trilayer sensor, with a composition of Ta (5 nm)/NiFe (10 nm)/Cu ( = 0 nm~1.

Slow Magnetic Relaxation, Antiferromagnetic Ordering, and Metamagnetism in Mn (H dapsc)-Fe (CN) Chain Complex with Highly Anisotropic Fe-CN-Mn Spin Coupling.

Reactions of [Mn(H dapsc)Cl ]⋅H O (dapsc=2,6- diacetylpyridine bis(semicarbazone)) with K [Fe(CN) ] and (PPh ) [Fe(CN) ] lead to the formation of the chain polymeric complex {[Mn(H dapsc)][Fe(CN) ][K(H O) ]} ⋅1.5n H O (1) and the discrete pentanuclear complex {[Mn(H dapsc)] [Fe(CN) ] (H O) }⋅4 CH OH⋅3.4 H O (2), respectively.

Relaxation dynamics of magnetization transitions in synthetic antiferromagnet with perpendicular anisotropy.

Two synthetic antiferromagnet bilayer systems with strong perpendicular anisotropy CoFeB/Ta/CoFeB and Pt/Co/Ir/Co/Pt have been grown using sputtering techniques. For both systems two types of magnetization transitions have been studied. The first one concerns transitions from a state where magnetizations of the two magnetic layers are parallel (P state) to a state where magnetizations of the two layers are aligned antiparallel (AP state).

A new Mo(iv) complex with the pentadentate (NO) Schiff-base ligand: the first non-cyanide pentagonal-bipyramidal paramagnetic 4d complex.

A heptacoordinate complex [Mo(DAPBH)Cl] (HDAPBH is 1,1'-(pyridine-2,6-diyl)bis(ethan-1-yl-1-ylidene)dibenzohydrazine) has been synthesized and characterized structurally and magnetically. It exhibits a slightly distorted pentagonal bipyramidal geometry and reveals paramagnetic behaviour resulting from two unpaired electrons (S = 1) with large positive zero-field splitting (D = +50 cm) and pronounced temperature-independent paramagnetism.
