For ferroelectric materials, perovskite compounds such as lead zirconate titanate (PZT) are widely used.
Au [9] and Ag alloys [10] have been used as top electrodes on PZT thin films for ferroelectric capacitors via PLD and dc sputtering, respectively.
Hence, the aim of the present study was to deposit various metal electrodes such as Au, Al, Ag and Cu on PZT films and to use the resulting materials as top electrodes.

Binary alloys.
We turn now to the case of binary K-Cs and Na-K alloys.
Nevertheless, results of Na-K and K-Cs alloys superimpose between 300 and 800 K.

It was reported that the LaFeAsO compound had superconducting properties with a critical temperature or Tc of ~26 K [2].
The FeSe-based bulk material can be synthesized using a conventional solid-state and mechanical alloying.
The sealed process was aimed to prevent the oxidation process of the iron during the heating process.

They belong to medium carbon low-alloy steel, and their representative steel are 3Cr2Mo and 3Cr2MnNiMo which are developed according to AISI P20 and AISI P20+Ni, respectively.
On the basis of 3Cr2Mo steel, a series of derivative steels have been independently developed, such as 3Cr2MoB, 3Cr2MoS, 3Cr2MoBS, 3Cr2MoSRE and 3Cr2MoBSCa, some of them are shown in Table 1 [4-6]. 0.001% ~ 0.003% B added into the 3Cr2Mo steel aims to increase the hardenability. about 0.1% S added into the 3Cr2Mo steel is to form MnS inclusions to destroy the continuity of the matrix and achieve high easy-cutting performance. 0.002% ~ 0.01% Ca Added into the 3Cr2Mo steel is to form S-Ca compound as the easy-cutting element.
Particularly they used the computer to simulate quenching process, and modified the traditional prehardened process into the air→water compound quenching process, which made 3Cr2Mo and 3Cr2MnNiMo mould steel blocks totally harden, and also reduced the possibility of the deformation and cracking [11,12].
Since 1992, Xiaochun Wu has researched and designed non-quenched prehardened plastic mould steel through study the alloying mechanism, microstructure control, processing properties, and invented the FT series of non-quenched prehardened plastic mould steel.

The temperature span of this effect is limited to only few degrees and the largest MCE is observed near a phase transition (PT); for example, this will be about 2 K/T for gadolinium near Curie point temperature [2] and 3.3 K/T for a FeRh alloy near its 1st order PT [3].
The entropy change of different magnetic compounds is studied in large number of works [4].
If we assume that τ has the same values for the intermetallic compound Fe49Rh51 with giant reverse MCE, then taking ΔS = 11.8 mJ/(g´K) at T = 297 K in a field of H = 20 kOe [3] we get: P = ΔS ∙ T ∙ f = 11.8 mJ/(g∙K) ´ 297 K ´ 11 Hz ≈ 38.5 W/g.

Introduction
There are some of type permanent magnet such as ferrite based magnet (Ba/SrFe12O19) , alloy based magnet (AlNiCo and SmCo) and rare earth based magnet (NdFeB) [1].
While ferrite-based magnets are also called as ceramic magnets because the components of the material are in the form of oxide compounds, the magnetic properties of ferrite based magnets are not very high, but it has a curie temperature of around 450oC and is very stable in atmospheric conditions or it has a good corrosion resistance [3,4].
The aim of this research is to create a hybrid bonded magnet Ba-ferrite / NdFeB system with Poly vinyl alcohol adhesive, and to know the effect of the comparison of Ba ferrite : NdFeB on physical properties, magnetic properties and corrosion resistance.
