Platinum magnetical properties

Platinum-cobalt alloys have magnetic properties. One such alloy made of 76.7% Pt and 23.3%... 

Pure platinum is malleable and ductile with excellent corrosion resistance. When alloyed with cobalt, it has good magnetic properties (76.7 W% Pt, 23.3 W% Co). 

Large platinum carbonyl clusters have been investigated as models for the adsorption of carbon monoxide on platinum surfaces and on platinum electrodes. An issue is how large the clusters must be before they adopt the properties of the bulk metal. Teo et al. have investigated the magnetic properties of the clusters [Pt6(CO)12]2+, [Pt9(CO)18]2+, [Pt y(CO)22f+, and... 

Iron-platinum and similar materials require a lot of energy to alter their magnetic properties, making these substances stable and a good... 

The first indications of covalency in complexes of two metal oxides appear if one of the metals belongs to the platinum group. The oxide complexes in this group are not well known only very recently a few complexes have been prepared and their magnetic properties measured. The compound Na2Ir03, that is formed when a mixture of the metal and Na2GOs is heated in oxygen... 

Magnetic Properties of the Platinum Metals and Their Alloys... 

In addition to the dilute alloys already discussed, there are a number of alloys of the metals of the platinum group with manganese, iron, cobalt, and nickel which have magnetic properties based on the formation of ordered structures at some particular composition. 

It will not be possible, in this paper, to deal with all of the platinum metal chalcogenides. Instead, a number of examples will be chosen and their electrical as well as magnetic properties correlated with the atomic positions in the various structures formed. The first group of compounds to be discussed crystallize with the pyrite structure, which is shown in Figure 1. This structure is similar to the NaCl structure if we replace Na by Fe and each Cl by an S2 group. However, the S-S distance within... 

Magnetic.—Density circa 14. The magnetic property appears to bear some relation to the percentage of iron contained in the alloy, but strict proportionality in n way exists.1 Some specimens of native platinum from the Urals, indeed, are said to attract iron filings even more powerfully than an ordinary magnet.
