Synthesis, magnetic properties, and colossal magnetoresistance ofEu13.97Gd0.03MnSb

Structure and magnetic properties of Ca14MnP11

“…In general, the structure can be understood within the Zintl formulism as composed of AlSb 4 9À tetrahedron, Sb 3 7À trimer, 4 Sb 3À anions, and 14 Ca 2+ cations. The main group-containing compounds are semiconductors and the Mn-containing compounds show unusual behavior such as long-range magnetic ordering and colossal magnetoresistance [5][6][7][8][9][10][11][12]. These magnetic properties are surprising considering that there are no possible mechanisms for orbital super-exchange and the tetrahedron are well separated.…”

Neutron Diffraction Study of the Ternary Transition Metal Zintl Compound Ca14MnSb11

“…The study also shows that the size of the metal cation and pnictogen element has a key role in determining the electrical and magnetic properties of the compound by changing the overlap of the anion wave functions resulting in a modified energy band gap. The continuous efforts to elucidate the magnetic properties of the compounds have been expanded to more complex systems, such as the rare-earth transition metal ternaries Eu 14 MnPn 11 (6,18,19), Yb 14 MnPn 11 (5,11), and the pseudo-ternaries Eu 14Àx A x MnSb 11 (A=Ca, Sr, Ba, Yb, Gd) (7,20,21).…”

Complex Magnetic Ordering in Eu3InP3: A New Rare Earth Metal Zintl Compound

“…[6][7][8][9][10][11][12][13] In addition, superconductivity has been discovered in several Zintl compounds. 5,13-15 Because of their unique magnetoresistive properties, [16][17][18][19][20][21][22] we have been exploring a flux synthesis * Author to whom correspondence should be addressed.
